Overview

This skill creates and configures hooks for Claude Code to automate workflows and extend functionality. It enables PreToolUse validation, PostToolUse logging/cleanup, and notification hooks to support auditing, security controls, and custom automation.

How This Skill Works

Hooks are defined and stored in ~/.claude/settings.json under the hooks key, using reference templates from references/CLAUDE_HOOK.template.md. The skill implements hook events (PreToolUse, PostToolUse, Notification, Stop) to cover validation, logging, alerts, and final reports, enabling configurable automation and safer tool interactions.

When to Use It

• Tool execution validation
• Audit logging
• Custom notifications
• Workflow automation
• Security controls

Quick Start

1. Step 1: Open ~/.claude/settings.json and add a hooks section
2. Step 2: Define PreToolUse, PostToolUse, and Notification hooks using references/CLAUDE_HOOK.template.md
3. Step 3: Test hooks independently and monitor performance to ensure <1 second latency

Best Practices

• Keep hooks fast (< 1 second)
• Handle errors gracefully
• Use specific matchers
• Test hooks independently
• Avoid verbose output

Example Use Cases

• Block tool execution when input fails validation rules (PreToolUse)
• Log tool outputs and perform cleanup after tool use (PostToolUse)
• Send alerts or notifications on notable tool events (Notification)
• Trigger downstream workflows automatically after a tool completes
• Enforce security controls by restricting tool usage through hooks
